Background technology
In distribution system, PT cabinets can only typically be monitored to system power supply situation, and rarely have to power supply protection, such mistake
Voltage suppression device PT shoves over the ground, overvoltage, resonance protection deficiency can frequently result in accident generation, such as PT fuses burn, PT
Blast, resonance overvoltage etc., and device back-up protection device, for example fuse be big heat device, its produce high heat
Also it is unfavorable for the protection of device.
The content of the invention
The utility model purpose is to provide a kind of Intelligent over voltage monitoring restraining device, realize various overvoltage in device,
It is decompression, under-voltage, shove over the ground, the monitoring of resonance overvoltage with protection while reducing apparatus in heat so as to reach further guarantor
Shield effect.
In order to realize the above object the technical solution adopted in the utility model is：A kind of Intelligent over voltage monitoring suppresses dress
Put, including cabinet, cabinet epicoele is provided with microcomputerized controller, lumen and is provided with disconnecting switch, cavity of resorption and is provided with fuse, cabinet
Cavity of resorption be additionally provided with overvoltage peak absorbing device, PT protection switch, anti-resonance potential transformer, described overvoltage spike is inhaled
Receive device arranged apart by dividing plate with fuse, described PT protection switch, anti-resonance potential transformer be located at fuse place every
In chamber, the first temperature sensor and the first cooling mechanism are set on the cabinet of the separate space, screen is equipped with the first temperature sensor
Cover is covered, second temperature sensor and the second cooling mechanism, second temperature sensor are set on the cabinet of the separate space where fuse
On be equipped with radome.
It is of the present utility model to have technical effect that：The microcomputerized controller installed in cabinet realize to apparatus system overvoltage,
It is decompression, under-voltage, shove over the ground, the collection monitoring of resonance overvoltage, and targetedly thrown according to the situation that various failures embody
Enter protection location to protect system.Wherein, the overvoltage peak absorbing device of setting suppresses overvoltage spike, lowers significantly residual
Pressure value, produced big energy during absorption system overvoltage powers off stream and reaches protection fuse and resist by PT protection switch
The effect of resonant voltage transformer, and the big component anti-resonance potential transformer of two quantities of heat production, fuse are located at two
The interior dispersion of separate space is installed, and reaches the scattered purpose of heat, and by adding first, second temperature sensor, constantly monitoring each
The heat of separate space, when the heat is excessive, by first, second cooling mechanism, reaches the effect of cooling protection.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Referring to the drawings, a kind of Intelligent over voltage monitoring restraining device, including cabinet 1, the epicoele of cabinet 1 is provided with microcomputer control
Device 2, lumen is provided with disconnecting switch 3, cavity of resorption and is provided with fuse 4, and the cavity of resorption of cabinet 1 is additionally provided with overvoltage peak absorbing device
5, PT protection switch 6, anti-resonance potential transformer 7, described overvoltage peak absorbing device 5 separates cloth with fuse 4 by dividing plate
Put, described PT protection switch 6, anti-resonance potential transformer 7 sets in the place separate space of fuse 4 on the cabinet 1 of the separate space
The first temperature sensor 8 and the first cooling mechanism 9 are put, radome is equipped with the first temperature sensor 8, where fuse 4
The cooling mechanism 11 of second temperature sensor 10 and second is set on the cabinet 1 of separate space, screen is equipped with second temperature sensor 10
Cover cover.
The microcomputerized controller 2 installed in cabinet 1 realized to apparatus system overvoltage, decompression, under-voltage, is shoved over the ground, resonance
The collection monitoring of overvoltage, and targetedly put into protection location system is protected according to the situation that various failures embody
Shield.Wherein, the overvoltage peak absorbing device 5 of setting suppresses overvoltage spike, residual voltage value is lowered significantly, during absorption system overvoltage
Produced big energy, the work that stream reaches protection fuse 4 and anti-resonance potential transformer 7 is powered off by PT protection switch 6
With, and two quantities of heat production big component anti-resonance potential transformer 7, fuses 4 are disperseed to install in two separate spaces, arrive
Up to the scattered purpose of heat, and the heat of respective separate space is constantly monitored by adding first, second temperature sensor 8,10, work as heat
When measuring excessive, the effect of cooling protection is reached by first, second cooling mechanism 9,11.
Further, described first cooling mechanism 9 include the air exhauster set positioned at separate space top and positioned at this every
The hair-dryer that chamber top is set.
The second described cooling mechanism 11 includes the air exhauster set positioned at separate space top and is set positioned at separate space top
The hair-dryer put.
Known, hot-fluid is that, to upstream, such first, second cooling mechanism 9,11 is taken out by the air exhauster that top is set
The cold air outside hair-dryer conveying that hot-air, lower section in separate space are set reaches the effect of cooling protection.
Preferably, ZnO resistors valve block is set in described overvoltage peak absorbing device 5.Using low dynamic oxidation zinc electricity
Resistance valve block, can substantially reduce residual voltage value.
